fix(cli/init): remove tmp 'node_modules' dir on init npm project

[edilson258]

Closes #29513

When creating a new project using deno init --npm <package> a temporary node_modules directory is created to store the package initializers scripts.

example:

deno init --npm solid

A temporary node_modules directory will be created to store the solid initializers scripts under node_modules/create-solid

This PR aims to delete that node_modules directory after initialization since it is not longer needed.

Some projects automatically install packages - this change would cause the installation process to be discarded. I'm -1 on this change.

Most likely what I think should happen instead is deno init --npm should implicitly run with the --node-modules-dir=none setting, but I'm not 100% sure. That way the node_modules directory doesn't get populated with the create-... package

i think everyone disagree with this patch, so we can close it right?
